Calculates the following:
Solves for r given n and the combination value.
Solves for n given r and the combination value

Calculates the following:
How many combinations can we have from a sample of r elements from a set of n distinct objects where order does matter and replacements are not allowed?

Shows the divisibility of a number by seeing if it is divisible by (2,3,4,5,6,7,8,9,10,11)

Given an ellipse equation, this calculates the x and y intercept, the foci points, and the length of the major and minor axes as well as the eccentricity.

Calculates the following factorial items:
* A factorial of one number such as n!
* A factorial of a numerator divided by a factorial of a denominator such as n!m!/a!b!
* Double Factorials such as n!!
* Stirlings Approximation for n!

Takes various functions (exponential, logarithmic, signum (sign), polynomial, linear with constant of proportionality, constant, absolute value), and classifies them, builds ordered pairs, and finds the y-intercept and x-intercept and domain and range if they exist.

Checks to see if a set of ordered pairs represents a function

Given a hyperbola equation, this calculates:
